Issue with /var/log - no space left (on zram)

[AZ8]

Time to time i got following notification on Banana Pi M1.  Only after reboot Banana starts working properly. How to tune zram to avoid such kind of issue? No tuning made till now

 

Linux bananapi 4.19.17-sunxi #5.73 SMP Mon Jan 28 21:06:40 CET 2019 armv7l GNU/Linux

# percentage of DRAM available to zram. If this amount is exceeded the zram

and where can I define the size of RAMLOG in particular?

@AZ8 you could also check if your system actually has to the patch for journald log-size in /var/log:
